What is a Dual-Class Stock Structure?

A dual-class stock structure basically means that a company has given disproportionate voting rights to one group of shareholders, typically its founders. In most companies, one share of stock equals one vote. But companies with dual-class structures give founders super-voting stock that may have 10 or more votes per share, though it’s treated the same as other common stock in terms of economic rights.

Dual-class structures are becoming more popular because a number of highly visible companies have implemented super-voting stock. Companies with visionary founders, like Facebook, Snap[1] and Alphabet, have put such structures in place as a means of preserving founder control.  As an example, Facebook has Class A shares and Class B shares. Investors hold Class A shares, but Mark Zuckerberg holds Class B shares, which have 10 votes each. His shares represent roughly 14% of Facebook’s economic ownership but control nearly 60% of the voting rights.  

A Look at the Math

Let’s take a quick look at how super-voting shares work in practice, in a company with two co-founders, a couple of key employees and other stockholders. Here, the founders only own 30% of the company, but control 81% of the vote:

  Shares % Ownership Votes Voting Power
Founder 1 100 Class A 10% 1,000 27%
Founder 2 200 Class A 20% 2,000 54%
Key Employee 1 50 Class B 5% 50 1.4%
Key Employee 2 50 Class B 5% 50 1.4%
Others 600 Class B 60% 600 16.2%
  1,000 Shares 100% 3,700 100%

Why Put in Place a Dual-Class Structure?

Whether a dual-class structure makes sense for a company is highly situation-specific. Founders that want to protect their vision[2] might pursue a dual-class structure that gives them the freedom to focus on long-term strategic projects.[3] As we all know, a founder with a successful business will have more negotiating leverage in implementing a dual-class structure: there’s more evidence that her leadership is important and there’s more demand from investors. But investors may balk at a mechanism that could entrench founders and shield them from accountability, and notable stock indices like the Russell 2000 and S&P 500 have changed their rules to make dual-class shares ineligible for inclusion.

Other Considerations

For a company that has decided to implement a dual-class structure, the first question is when to implement it. Many companies with dual-class stock structures adopt them late in their lifecycle, often immediately prior to their initial public offering, rather than at incorporation.

The second question is when to end the dual-class structure. Often the company’s governance documents provide that the super-voting shares convert into regular shares upon a transfer, or if the founder’s total ownership percentage drops below a specified threshold. The dual-class structure can also include a “sunset” provision that removes super-voting rights after a period of time.


[1] Snap went public by selling shares of common stock with zero voting rights. The founders and early investors held voting stock.

[2] Other methods of protecting founders include (1) director super-voting rights, allowing an individual director more than one vote; (2) founder protective provisions, giving the founders veto rights over certain key decisions; and (3) large severance packages, forcing the business to pay a pre-set cash amount to a founder on termination.

[3] This concern is often more relevant to public companies, which are dealing with the pressures and incentives of short-term owners and the liquid public markets, and not to private companies.
